zales, at the Hacienda Carpuela, at an altitude of 
5,300 feet. This is a good-sized Mexican avocado 
of excellent quality. The seed is relatively quite 
small, and the tree is said to be very productive. 
The fprmof the fruit is obovoid, the color purple. 
Commonly it weighs about 9 ounces. The variety is 
well worthy of a trial in California, and in the 
cooler avocado-growing regions of Florida."

54279. "No. 623. 'Mora comun. ' Prom the Ha- 
cienda La Rinconada, in the province of Carchi , at 
an altitude of about 11,000 feet. This is a very vig- 
orous Rubus, forming large clumps up to 15 to 18 
feet high. Its stout canes are thickly clothed 
with short, stiff, bright maroon-colored hairs, 
while its leaves are formed of five leaflets 3 to : 
4 inches long. The white flowers are produced in 
large, loose .clusters which are sometimes more than 
a foot in length, and are followed by an abundance 
of oval, deep purple fruits about three-quarters 
of an inch long. The seeds are moderately large, 
but not very troublesome in the mouth. The flavor 
Is practically the same as that of the cultivated 
blackberry of the North, and the quality Is good. 
Because of its productiveness as well as this 
latter feature, the species is worthy of a trial 
in the southern and western United States."

berry), 'from the Hacienda La Rinconada, Province 
of Carchi, where it occurs as a wild plant, at al- 
titudes of about 11,000 feet. This species of Rubus 
is low-growing, half -shrubby in habit, sending upt 
canes to a height of 6 to 8 feet. The stems are 
light green, covered with short stiff hairs; the 
leaves are oomposed of five smooth leaflets 3 to 4 
Inches long. The white flowers, about an inch 
broad, are borne in many-flowered clusters up to a 
foot long. The fruits are abundantly produced; they 
are oblong to oval, up to three-quarters of an Inch 
long, and cream-white when ripe. The seeds give 
little trouble when the fruit is eaten. The flavor 
of this excellent berry is sweet and pleasant; the 
species is, in fact, one of the most Interesting 
and promising of all the forms of Rubus . I have;
